Subject: Is gcc 3.2.2 suitable for kernel builds?

It seems that some gcc 3.2.2 optimizations are generating
bogus code sequences.

Has anyone else had compiler issues w gcc 3.2.2?

Thanks much,

johnh

I'm using gcc 3.2.2 and everything is "ok". What optimization are you
using? Maybe you will upgrade to 3.2.3?

As recently posted in a thread "gcc 2.95.3", please have a look at
http://developer.osdl.org/cherry/compile/

3.2.2 and 2.6.x should work fine under most circumstances.

What kernel-version, optimizations and architecture are you using?
